Pre-Gait Activities Flashcards
(32 cards)
What is involved in prosthetic training
- Pre-prosthetic training and preparation
- Care of prosthetic componentes and residual limb
- Donning/doffing of prostheses
- Assessment of prosthetic fit
- Pre-gait activities and training
- Gait training/assessment and environmental negotiation
- Gait dysfunction/patterns
- Outcome measurement
What is involved with prosthetic preparation
- Protect incision/residual limb integrity
- Regular skin checks
- Shaping of the residual limb
- Scar mobilization
What are the components of a prostheses that requires care
- Linear/nylon sheath
- Socks
- Prosthesis itself
4 steps of component care
- Hand wash with mild soap and water
- Rotate daily and allow to dry overnight
- Remove any debris
- Check for uneven areas/holes and replace when worn
Describe prosthetic socks
- Different thicknesses/ ply
- Most common is 1, 3, and 5 ply
- You have to add them together to get the total ply
- Goal is to wear the least number of socks to get the correct ply.
- Educate the patient to always carry multiple socks and they will need to adjust ply during the day.
Prosthetic donning
- Safest if performed initially in sitting
- Most patients will need to stand to get all the way down into the socket but want to don most things in seated
- Start with liner -> don correct number of socks for a snug fit but able to drop all the way into the prosthetic
- Don thickest sock first progressing to thinnest — its easier to adjust ply later
Trans-tibial donning
- Angle of prosthesis with knee flexed to 30-45 deg
- Align patella with patellar cut out
- Gently push down on knee or slide down into socket to engage suspension method (shuttle lock, suction, vacuum)
- Stand and weight shift to slide down to final resting position
Trans-femoral donning
- Don in sitting if possible
- Slide into socket as far as possible
- Attach socket to limb via suspension mechanism (suction, vacuum, strap)
- Stand to lock into prosthesis/get to final resting position — requires good dynamic balance
- Lock knee in standing prior to weight shifting.
How do you assess a transtibial prosthetic fit
- Assess in standing
1. Patella lined up with cut out
2. Supracondylar ridges over femoral condyles
3. Patellar tendon just above patellar bar
4. Tight fit between socket and residual limb
5. Not bottoming out
How do you assess transfemoral prosthetic fit
- Assess in standing
1. Bend forward to assess ischial tuberosity
2. Abduct prosthesis to palpate public ramus.
What are other prosthetic fitting observations
- Pelvic alignment — want symmetry of iliac crests and ASIS
- TF socket — flex, add, wall height
- TT socket — IR/ER, valgus/varum, supracondylar trims
- Feet — prosthetic foot flat on floor, slight toe out, PF/DF
Steps for doffing prosthesis
- Performed in sitting
- Disengage locking/suspension mechanism
- Slide off prosthesis
- Take off socks/sleeve
- Skin inspection (can use handheld mirror)
General skin inspection tips
- Total surface bearing and transfemoral = look for general redness and reports of discomfort, should not be over areas of bone prominences
- Note amount of sweating or any rashes
- Redness should dissipate within 20-30 minutes
- Educate patient on expected areas of redness
- Put compression method back on or rewrap
Transtibial pressure tolerance areas
- Patellar tendon
- Supracondylar areas
- Tibial flares
- Hamstring muscle/posterior residual limb
Transtibial pressure INtolerance areas
- Femoral condyles
- Patella
- Tibial tub
- Tibial crest
- Fibular head
- Anterior/distal ends of tibia and fibula/incision line
Transfemoral pressure tolerance areas
- Ischial tub
- Around the middle of the residual limb
- Distal end of the residual limb
Transfemoral pressure INtolerance areas
- Greater trochanter
- Pubic ramus
- ASIS
- Adductor tendon
- Distal femur
- Pubic tubercle
- Incision
Other skin inspection tips
- Unexpected areas of discomfort or redness
- Compare to pressure tolerant areas
- Consider patient causes and donning techniques
- Look at prosthetic and LE alignment
Prosthesis wear schedule
- Start 1-2 hour wearing with weight bearing no more than 20-30 minutes.
- Then 1-2 hours off and repeat (use shrinkers when not wearing it)
- Typical progression 30-60 minutes increase every 2-3 days
- Progression depends on tolerance and how quickly redness dissipates
- Progress activity level and wear time separately
Patients may have difficulty achieving weight bearing through prosthesis during sit to stand if…
- TTprosthesis knee cannot flex far enough for the foot to be flat on floor
- TF prosthetic knee cannot provide knee extension force, must be locked for stability
What are the goals of pre-gait training in this population
- Increase weight t bearing through the prosthesis
- Decrease deviations
- Increased patient confidence and kinesthetic awareness
- Learn how to control the components
Stand to sit considerations for transfemoral patietns
They may have to unlock the knee prior to sitting
- method of stand to sit depends on the type of knee joint they have
Why is it important to normalize weight bearing with a prosthetic
- Normalize gait patterns
- Increased proprioception through prosthesis
- Protection of the sound limb
- Fall prevention
- Prevention of lumbar dysfunction (pelvic rotation is big weakness for these patients)
Examples of weight bearing exercises
- Static balance with intact foot on step — can progress with a foam pad
- Intact foot taps on step
- Weight shift COM (usually belly button) over prosthesis
- Marching — go from a firm surface to more compliant
- Single limb stance
